The ongoing rise of human computation as a means of solving computational problems has created an environment where human workers are often regarded as nameless, faceless computational resources. Some people have begun to think of online tasks as a "remote person call". In this paper, we summarize ethical and practical labor issues surrounding online labor, and offer a set of guidelines for designing and using online labor in ways that support more positive relationships between workers and requesters, so that both can gain the most benefit from the interaction.

There is great interest in understanding media bias and political information seeking preferences. As many media outlets create online personas, we seek to automatically estimate the political preferences of their audience, rather than of the outlet itself. In this paper, we present a novel method for computing preference among an organization's Twitter followers. We present an application of this technique to estimate political preference of the audiences of U.S. media outlets. We also discuss how these results may be used and extended. Copyright 2011 ACM.

Event sequence analysis is an important task in many domains: medical researchers may study the patterns of transfers within the hospital for quality control;transportation experts may study accident response logs to identify best practices. In many cases they deal with thousands of records. While previous research has focused on searching and browsing, overview tasks are often overlooked. We introduce a novel interactive visual overview of event sequences called LifeFlow. LifeFlow is scalable, can summarize all possible sequences, and represents the temporal spacing of the events within sequences. In this video, we show an example of patient transfer data and briefly demonstrate how to analyze them with LifeFlow. Please see [11] or visit http://***/hcil/lifeflowformoredetail.

People want to do more with their mobile phones and every day new mobile applications are launched in a increasingly wide number of domains. However, traditional UI knowledge is not sufficient to design effective interfaces for mobile applications because the mobility context presents developers with several peculiarities and new challenges. This tutorial will introduce participants to the design of visual interfaces for mobile applications. In particular, it will: (i) illustrate the peculiar aspects of mobile interaction that make it more difficult to build effective user interfaces for mobile users, (ii) show how the powerful graphics capabilities of today's mobile devices can be exploited to create interfaces that help users on the move do more with their phones, requiring less time and attention,. (iii) look at recent developments in the engineering of mobile UIs such as tool support for mobile interface development, including mobile end-user programming. Copyright 2011 ACM.

Today's mobile devices are natively equipped with multimedia means for children to capture and share their daily experiences. However, designing authoring tools that effectively integrate the discrete media-capture components of mobile devices to enable rich expression remains a challenge. We report results of a study on the observed use of StoryKit, a mobile application that integrates multimodal media-capture tools to support the creation of multimedia stories on the iPhone/iPod Touch/iPad. The primary objectives of the study were to explore the ways in which StoryKit enables individuals to create and share personal stories;and to investigate how the created stories themselves might inform the design of mobile storytelling applications. Its results suggest that StoryKit's relatively simple but well-integrated interface enables the creation of vibrant, varied narratives. Further, genre analysis of the types of stories created revealed a surprising volume and diversity of use in educational contexts.

Pulitzer Prize-winning journalist Nicholas Kristof argues that "in this century the paramount moral challenge will be the struggle for gender equality around the world." In this paper, we present a design model for empowering low-income women in the developing world, in ways that cut across individual application areas. Specifically, this model characterizes a possible trajectory for NGOs and women to engage with each other and among themselves - potentially augmented by technology - to help women escape from poverty. The fieldwork components in this study took place over 15 weeks in three phases, with a total of 47 NGO staff members and 35 socio-economically challenged women in rural and urban India. Interviews and co-design sessions with seven proof-of-concept prototypes showed that women appeared to belong to five distinct stages of "growth" in striving towards independence. We report the technology design lessons from our co-design sessions to illustrate how user readiness, relationship building at the community and family levels, and integration with state, national and international level programs, should be taken into account in the broader context of intervention design.
